BED-PLATE FOR SUVLKY-QPLOW BEAMS.

SPECIFICATION forming part of Letters Patent No. 293,939, dated February 19, 1884.

' Application filed November 26, 1883. (No model,)

. Figure 1 is atop or plan view, showinga section of the bail with the bed-plate thereon; Fig. 2, a bottom'plau View of the bed-plate; Fig. 3, a longitudinal section of the bed-plate with the locking-washer in position to allow the beam to swing and turn; and Fig. 4, a 1011- gitudinal section of the bed-plate with the locking-washer'in position to hold the beam rigid.

The object of this invention is to construct.

a bed-plate or support for the attachment of a sulky-plow to its bail, either to leave the plow free to swing or turn laterally or be held firmly and in alocked position; andits nature consists in providing a bed-plate to be attached to the plow-beam,and a box or socket to be attached to the bail, combined with a fastening-bolt and a washer, having on one face projecting lugs to enter recesses in the box or socket, all as hereinafter more specifically described, and pointed out in the claim. In the drawings, A represents the beamplate, made of malleable iron or other suitable material, and having on its upper face, at each end, lips or, between which there is a recess, a, of the required width for the width of beam, and having, as shown, midway of its length openings 12 for the passage of astirrup or clip, by which the plate is firmly attached to the beam. This plate, at its forward end, has a circular stud, c, with a central opening for the 4 passage of a bolt. The end face of this stud or bearing 0 has a square recess, d, and the face of the plate A is provided with a square recess, (1 which receives the head of the bolt by which the plate A is pivotall y attached to the bail-socket.

BB represent the bail socket or box, made of malleable iron or other suitable material. This box is made in halves or sections, each section having a half-circular depression, to form, when together, .an opening, B, corresponding in diameter to the diameter of the through the ears and plate B on the opposite side, as shown in Figs. 2 and 3 The under face of the plate B is provided with an annu' lar rim, h, in which are formed recesses h, which recesses are in line with each other on opposite sides of the flange.

O is a disk or plate of a circular form, as shown, and having at its center, on each side, a square or rectangular lug or projection, 2', through which and through the plate is a circular-opening for the passage of the stemof the connecting-bolt, and this plate on one face at its periphery is provided with lugs i, so arranged as to enter the recesses h when the parts are in the position shown in Fig. 4'. The lug or projection i on either side of the plate 0, when the parts are together, enters the square or rectangular recess d in the end of the stud or bearing 0, connecting the plate 0 with the plate A, the connection being one which looks these two plates together.

D is a bolt, the stem of which passes through the opening in the plate A, stud c, and plate 0, as shown in Figs. 3 and 4, and when the parts are together the head of the bolt D is in the recesses d, and its nut is in contact with the end'of the stud iof the exterior face of the plate G.

E is the bail which carries the plow, which bail may be of any of the ordinary forms of construction.

In use, when it is desired to have the plow loose to swing or turn laterally, the washer or plate 0 is turned to bring its smooth face in contact with the rim or flange 71, as shown in Fig. 3, in which. position the stud or bearing 0 is free to turn, allowing the beam and plow to swing or turn laterally on this stud or bearing as a pivot. WVhen it is desired to hold the plow rigid, the washer or plate 0 is turned or reversed, as shown in Fig. 4, in which position the lugs i enter the recesses h and lock 2 assess the plate 0 to the extension 13", and this 6X- tension being socketed on the bail, and at the same time the stud i being in the recesses d, with the head of thebolt D in the recesses d. the plate A and washer or plate 0 are locked together and to the extension 13, preventing any lateral turn or swing of the beam, and holding the parts together as one piece.

The device is very simple in its construction and operation, and all that is required to change from a loose to a rigid beam, or-vice versa, is to remove the nut of the bolt D, apply the plate or washer C, to cit-her form a lock or allow a free lateral turning on the stud or bearing 0.

As shown, the device is constructed and an. ranged to carry an overhung beam; but it is evident that an underhung beam can be carried in the same manner, to be loose or locked,

by reversing the position of the plates A O 20 and changing the flange 71 to the upper side of the plate B Instead of using a square or rectangular stud, i, at the center of the plate 0, on each side, two studs or pins on each side could be used, in which case the end of 0 should have corre sponding holes to receive the studs or pins.

W'hat I claim as new, and desire to secure by Letters Patent, is as follows:

In a coupling for sulky-plow beams, the plate A and socket or box B B, having an extension, 13", in combination with the reversible plate 0 and bolt 1), substantially as and for the purpose specified.
